World "shared" Xp And Loot

When you and another guy kill a mob together, it shows something like:
+4000 xp [Shared]

Then I thought we could add some more info to that... something like:
+3044 xp (Player1)
+956 xp (Player2)

And then why not do this system for loot as well?
Say a mob drops one "Sharp Claw" for Player1 and one "UnIDed Bow" for Player2, then there would be a tiny little nametag thingamabob above each item, saying which item belongs to whom. And then each individual player picks up the item belonging to them. Perhaps this can cause lag, so it may not work in that way...
